How to achieve a blur effect in PHP?

Question

I\'ve been looking for PHP code to apply a Gaussian blur to images.

What I\'ve done was like this:

Answer 1

It is possible also without ImageMagic lib;

header('Content-Type: image/png');

$blurs = 10;
$image = imagecreatefrompng('blur.png');
for ($i = 0; $i < $blurs; $i++) {
    imagefilter($image, IMG_FILTER_GAUSSIAN_BLUR);
}
imagepng($image, 'blur10.png');
imagedestroy($image);

After 10 blur applied;
